Check the error massage first. What was the error message when you did the smitty and it only increased 100 GB instead of 200GB? If it complained about excess the max space or something like that, then you just need to change the MAX pv for ndbvg, and add 100GB more afterward. If you didn't see any error message, and after smitty, the total FS size became 500GB instead of 600GB, then make sure you've filled in the right number in 512 -byte block.
Your ndbvg shouldn't be striping since you only have /db/run, one lv, I think you should be able to increase it just simply through smitty. But do make sure that the ndbvg is not stripping.
There are some attributes of the vg that can be change without backing up anything, but pp size is not one of them.

blockdev
BLOCKDEV(8) System Administration BLOCKDEV(8)
NAME
blockdev - call block device ioctls from the command line
SYNOPSIS
blockdev [-q] [-v] command [command...] device [device...]
blockdev --report [device...]
blockdev -h|-V
DESCRIPTION
The utility blockdev allows one to call block device ioctls from the command line.
OPTIONS
-q Be quiet.
-v Be verbose.
--report
Print a report for the specified device. It is possible to give multiple devices. If none is given, all devices which appear in
/proc/partitions are shown. Note that the partition StartSec is in 512-byte sectors.
-h, --help
Display help text and exit.
-V, --version
Print version and exit.
COMMANDS
It is possible to give multiple devices and multiple commands.
--flushbufs
Flush buffers.
--getalignoff
Get alignment offset.
--getbsz
Print blocksize in bytes.
--getdiscardzeroes
Get discard zeroes support status.
--getfra
Get filesystem readahead in 512-byte sectors.
--getiomin
Get minimum I/O size.
--getioopt
Get optimal I/O size.
--getmaxsect
Get max sectors per request
--getpbsz
Get physical block (sector) size.
--getra
Print readahead (in 512-byte sectors).
--getro
Get read-only. Print 1 if the device is read-only, 0 otherwise.
--getsize64
Print device size in bytes.
--getsize
Print device size (32-bit!) in sectors. Deprecated in favor of the --getsz option.
--getss
Print logical sector size in bytes - usually 512.
--getsz
Get size in 512-byte sectors.
--rereadpt
Reread partition table
--setbsz bytes
Set blocksize. Note that the block size is specific to the current file descriptor opening the block device, so the change of block
size only persists for as long as blockdev has the device open, and is lost once blockdev exits.
--setfra sectors
Set filesystem readahead (same like --setra on 2.6 kernels).
--setra sectors
Set readahead (in 512-byte sectors).
--setro
Set read-only. The currently active access to the device may not be affected by the change. For example filesystem already mounted
in read-write mode will not be affected. The change applies after remount.
--setrw
Set read-write.
